STMicroelectronics 74VHCU04MTR

Overview

74VHCU04MTR from STMicroelectronics is a high-speed CMOS hex inverter with single-stage architecture, designed for digital logic inversion and analog oscillator circuits. It delivers 3.5 ns typical propagation delay at 5V, operates from 2V to 5.5V, supports 8 mA output drive, and features power-down input protection enabling 0–7V input tolerance regardless of VCC.

For engineers reviewing the 74VHCU04MTR datasheet, 74VHCU04MTR pinout, 74VHCU04MTR application, or 74VHCU04MTR equivalent, key selection criteria include TTL-compatible input thresholds, symmetrical output impedance, latch-up immunity, ESD robustness (2 kV), and rail-to-rail input voltage acceptance beyond supply rails.

Technical Context

The device implements six independent single-stage inverters using sub-micron C2MOS technology, enabling use in crystal oscillator feedback loops due to its unbuffered, low-capacitance signal path. Its input structure accepts voltages from −0.5 V to VCC + 0.5 V, and all inputs/outputs include diode-based ESD protection rated to ±2 kV per HBM.

DC switching thresholds are fixed at 0.2VCC (VIL) and 0.8VCC (VIH), ensuring compatibility with both 3.3V and 5V systems. Propagation delays are balanced (tPLH ≈ tPHL), and output drive strength is symmetric: |IOH| = IOL ≥ 8 mA at VCC = 5V with VOH ≥ 4.0 V and VOL ≤ 0.44 V under load.

FAQ

Can 74VHCU04MTR be used in a crystal oscillator circuit?

Yes. Its single-stage inverter architecture, low input capacitance (≤10 pF), and rail-tolerant inputs make it suitable for Pierce oscillator configurations. External crystal and load capacitors complete the resonant loop, and no external bias resistors are needed due to built-in DC path control.

What is the maximum input voltage allowed when VCC = 0 V?

Inputs tolerate −0.5 V to +7.0 V regardless of VCC state. With VCC = 0 V, the device remains undamaged and functional for input signals up to 7 V, thanks to integrated diode clamps and power-down protection-enabling safe hot-swap operation.

Does 74VHCU04MTR support 3.3V and 5V logic simultaneously?

Yes. Its TTL-compatible input thresholds (VIH = 0.8VCC, VIL = 0.2VCC) and wide VCC range (2–5.5 V) allow direct interfacing: a 5V-output device can drive its inputs at VCC = 3.3V, and its outputs swing rail-to-rail within the 3.3V domain.

How does its ESD protection compare to standard 74HC04?

74VHCU04MTR provides 2 kV HBM ESD immunity via integrated protection diodes on all I/O pins. Standard 74HC04 typically offers only ~200 V HBM unless externally protected-making the VHCU variant more robust for manufacturing, handling, and field-deployed industrial systems.
